The spontaneous decay of a heavy atomic nucleus of mass M = 16.5 ? 10?27 kg that is initially at rest produces three particles. The first particle, with mass m1 = 6.64 ? 10?27 kg, is ejected in the positive x direction with a speed of 1.70 ? 107 m/s. The second particle, with mass m2 = 3.40 ? 10?27 kg, is ejected in the negative y direction with a speed of 2.00 ? 107 m/s.
(a) What is the velocity of the third particle? (Enter the
magnitude.)
____ m/s
(b) What is the increase in the kinetic energy of the system after
the decay?
____ J

Alpha particles which have a charge +2e and mass 6.64 x 10-27 kg are initially at rest and are fired directly at a stationary platinum nucleus (charge +78e) at a speed of 2.75 x 10 m/s. Determine the distance of closest approach (in fm) before the alpha particle reverses direction. Assume the platinum nucleus remains stationary. Assume the alpha particles are initially very far from a stationary platinum nucleus. fm

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...
